电脑上网变得好慢，有以下的情况，请问是什么问题？
1 我打开百度首页，浏览器经常提示，正在发送请求。半天才上，或者直接上不了，打开的网页不敢刷新，怕过一下出不来.
2 我的问公司的网管，他在路由器那里看了，说我超过了最大连接数，所以上网很卡，叫我把Foxmail 之类的东西关掉。
3 我自己用 Netstat 看了我的端口，发现经常有一段连续的端口，如 211X 到 219X的端口连着好几个相同IP的 http端口，状态是以下 SYN_SENT,LAST_ACK，ESTABLISHED或者其他FIN_WAIT_1之类（也可能是其他端口）
4 我上网查了一下，这个好象是DDOS攻击，我下了一个叫冰盾，可能没有用，他里面有一个网卡的选项，我点了一下下拉框，一个网卡没有出来。
以下是我自己用netstat 输出的文字，红色就是我说的地方。

[解决办法]
中毒了吧，，，你用命令netstat -nao 查看发送连接的pid进程号，，在在进程管理器里打开pid查看，，找出那个程序，然后想办法把它关掉，用杀毒软件杀掉。
[解决办法]
对比你和公司其他人浏览网页的速度，看是否是由网速引起。。。。。
[解决办法]
试试autoruns软件。
[解决办法]
首先用icesword查看有没有陌生进程
系统进程就那么几个如果不知道那些是系统进程的话请百度
然后用intoruns删掉一些不必要的启动项
